Soil type data of Sichuan Tibet traffic corridor (1995)

Soil type data of Sichuan Tibet traffic corridor (1995)

According to the soil map of the people's Republic of China (1:1 million) compiled and published by the national soil survey office in 1995, the spatial distribution data of soil types in the transportation corridor between Sichuan and Tibet are generated digitally. The traditional "soil genetic classification" system is adopted. The basic mapping unit is subclass, which is divided into 12 soil classes, 61 soil classes and 227 subclasses. There are 2647 records and 16 attribute data items in the soil attribute database, covering all kinds of soil and its main attribute characteristics in China.
